Description :

The invention relates to an operating handle for a

Avalanche rescue system, a functional unit of a

Avalanche rescue system with at least two functional elements, which are coupled via a trigger system with an operating handle according to the invention, and an avalanche rescue system.

Every year, many people die as a result of one

Avalanche. Particularly affected are groups of people who engage in sports in unsecured alpine terrain. To the

To increase the survival of these individuals, emergency systems have been developed to increase the chances of survival. For example, it is known to provide an inflatable buoyancy device in the manner of an airbag on an emergency system. A user may initiate inflation of the buoyant body to increase its surface area.

This should make it possible that the winter sportsman who has triggered the buoyant body, moves up in the avalanche and thus is not spilled too deeply. Furthermore, it is known to provide a balloon which is inflated in an emergency and should also float, so that the

spilled, associated with the balloon winter sports can be found. Such a system is for example from the

EP 0 931 567 A2. The problem with this system is that on the one hand the operating handle for triggering the functional elements

(Buoyancy body and balloon) ergonomically unfavorable.

Another downside to this system is that a spilled one

Winter sports can suffocate, since no possibility is provided to ventilate the winter sports enthusiasts.

The object of the present invention is to provide a system with which the chances of survival of an avalanche spilled

Winter sports can be increased.

This object is achieved according to the invention by an operating handle for an avalanche rescue system, with at least one

Functional element of the avalanche rescue system can be coupled and with which a functional element can be triggered, wherein the handle is formed at one end as a mouthpiece or has such, which with a

Ventilation function unit can be coupled. The actuating handle can thus be used on the one hand to trigger the ventilation function unit. On the other hand, the handle can be used to ventilate a spilled winter sportsman. The fact that the mouthpiece is integrated into the handle, a winter sportsman must perform only a single movement, both to trigger the ventilation function unit and the other to lead the mouthpiece in the mouth. While in the prior art may have been such that on the one hand a mouthpiece in the mouth out and on the other a functional element are triggered must, so only one more action is necessary. By feeding the mouthpiece to the mouth, the functional element

to be triggered. A winter sportsman therefore only has to concentrate on a single action and not perform several actions. The chances of survival of a spilled winter sportsman can be significantly improved thereby.

The mouthpiece can be made of a limited yielding material

be formed so that a user can bite into the mouthpiece without being able to fully compress it.

According to one embodiment, the handle may be substantially T-shaped, with an air passage extending in one leg. When the handle is substantially T-shaped, it can be gripped more easily. For example, one leg of the Ts can be gripped with the index finger and the other leg of the Ts with the middle finger and ring finger. Preferably, the area with the two legs of the Ts is angled relative to a third base leg. This improves the ergonomics.

The fact that a leg has an air duct, can be breathed by the handle and the ventilation function can be realized.

The mouthpiece can via a flexible connector with the

Be connected actuating handle. In particular, the mouthpiece can be slightly removed from the handle, which is possible through the flexible connector. The mouthpiece can then be arbitrarily displaced or rotated relative to the handle in order to be able to supply it optimally to the mouth. The connecting piece can be designed, for example, as a hose, in particular as a concertina-type hose. To prevent injury to the mouth by rotation of the trigger handle or impact on the trigger handle due to avalanche, the mouthpiece is preferably flexibly attached to the handle. In order to change the mouthpiece, it can be arranged detachably on the handle.

The actuating handle may be formed hollow in sections. In this case, in the operating handle further components of the

Avalanche rescue system are arranged, for example a

Mechanism for triggering the functional elements.

A hose connected to the respiratory function unit may be partially parallel to a portion of the operating handle

run. For example, the hose outside of

Operating handle parallel to a portion of the actuating handle and then open into the operating handle, so that a fluidic connection with the mouthpiece is made. Alternatively, you can

be provided that the hose runs in sections in the operating handle. This has the advantage that the tube is arranged protected in the operating handle. Also, a connection to the mouthpiece can be easily realized.

In order to prevent the operating handle or the mouthpiece is clogged by heavy snowfall, a lid or a cap for covering the mouthpiece as needed can be provided. As a result, the reliability can be increased.

Further advantages arise when fastening means are provided for releasably securing the handle to a carrier system.

For example, the attachment means may be adapted to attach the handle to a carrier strap of a backpack. This has the Advantage that the handle must be arranged only when needed on the carrier system. In particular, it can be provided that a backpack in which the functional elements of the avalanche rescue system are arranged, separated from the avalanche rescue system and Beispie! can be used in the summer without the avalanche rescue system. For this purpose, it is advantageous if the operating handle can be released from the carrier system. The attachment can be done via a locking joint. This may have corresponding grooves with which it can be placed on piping on a carrier belt. In this type of attachment, the handle can also be adjusted along the carrier belt so as to be optimally positioned for a user can.

Furthermore, it can be provided that the actuating handle can be fixed in the region of the chest of a user. In particular, a

Breastplate be provided to which the operating handle can be attached.

It is particularly advantageous if the actuating handle is designed to be variable in length, in particular telescopic, at least in one section. This makes it possible to keep the handle relatively small when it is clear that it will not be needed. On the other hand, the handle can be extended and thereby increased so that it is safer to grip. The extended position is therefore preferably taken when the winter sportsman goes into avalanche prone area.

Further advantages arise when a locking mechanism for

Determination of the handle is provided in a length-changed position. In particular, it can be provided that the handle is automatically fixed in this position in its extended position. The determination can be made such that a user receives haptic feedback, that the handle is fixed in its extended position. The handle can in its different positions on the breast plate, z. B. by means of Velcro, fixed.

It is particularly advantageous if at least one opening is provided on the handle, through which used breathing air can escape.

In particular, it can be provided that breathing air and spent breathing air are conducted separately in order to prevent mixing.

The actuating handle may be multi-part, wherein at least a part is removable. Also, the breathing tube can be releasably connected to the removable part.

In order to increase the reliability, it can be provided that the surface of the actuating handle is at least partially executed with increased static friction. For example, the surface of the

Be operating handle gummed. Alternatively, it is conceivable that the

Surface of the operating handle has a part of a hook and loop fastener. In this case, the actuating handle either a loop tape or a hook tape, have, while on a glove of a user, the counterpart, ie loop tape or hook tape can be provided. Even with inaccurate or hectic gripping of the operating handle thus triggering of the functional element can be ensured. It is prevented that a user slips on the operating handle.

In the context of the invention also falls a functional unit of an avalanche rescue system with at least two functional elements which are coupled via a trigger system with an actuating handle according to the invention and simultaneously triggered by actuation of the actuating handle. One of the functional elements is a

Ventilation functional unit. It can thus have multiple functional elements be triggered simultaneously, the mouthpiece is guided on the operating handle at the moment of triggering of the functional element from the user to the mouth. It is thus only a single movement necessary to trigger both the functional elements and to guide the operating handle to the mouth. The reliability of an avalanche rescue system is thereby increased.

The triggering system may include a cable that branches at one end into strands that lead to the individual functional elements. Such a cable can at its unbranched end with the

Actuating handle are coupled. Preferably, the cable has a rigid jacket in the longitudinal direction, so that a Bowden cable is realized.

Alternatively, it is conceivable that a number of functional elements corresponding number of cables is provided, which with the

Actuating handle are coupled. Such a triggering system may be more reliable. If one of the cables breaks, the other functional elements connected to the other cables may still be triggered. On the other hand, if in the alternative embodiment the unbranched cable pull breaks, under certain circumstances no functional element can be released.

At least a cable and a breathing tube can

partially guided in parallel and surrounded by an insulation sheath. As a result, they are arranged protected. The cable can be part of an electronic trip system. Alternatively, it is conceivable that an activation cable for electronic triggering of at least one functional element is provided in addition to or as an alternative to the cable pull. According to an advantageous embodiment of the invention can be provided that as functional elements a ventilation function unit, a buoyancy body function unit and a balloon comprehensive

Positioning function unit are provided. Thus, in one

Function unit combines three functional elements. This is not known from the prior art. Every single one of these

Functional elements increases the chances of survival of a spilled winter sportsman. The buoyant body can preferably so

be designed to be wider than the shoulders of a buried person after being inflated. In addition, it can be shaped to protect and stabilize the neck area of a winter athlete to prevent spinal injuries.

The balloon may preferably be attached to a particular elastic rope which is wound on a pulley. The pulley is preferably attached to the user or to a support system. The fact that the rope is wound on the pulley, a can

undisturbed unwinding be ensured. A tangling of the rope can be prevented.

The rope of the balloon can be marked in color. For example, three different colors may be provided. By the color marking, a rescue team can see how deep the casualty

Winter sportsman is spilling.

Particular advantages arise when the functional elements can be arranged on a carrier system, in particular a backpack

Functional element carrier are arranged. This is for each

Function element provided a defined space. The functional safety can be increased. In addition, the entire functional element carrier including functional elements can be easily removed from a backpack or inserted therein. A rucksack can thus also be used, for example, in summer after the functional element carrier has been removed.

The functional element carrier can recesses at least for

Have components of the functional elements. As a result, the components of the functional elements are arranged protected.

The functional element carrier may have a recess for a probe and / or an avalanche blade. Thus, on

Functional element carrier also provided elements that can use a winter sportsman to locate and rescue other injured winter athletes.

The buoyant body is preferably connected to the functional element carrier. Furthermore, fastening means for releasably securing the functional element carrier in a carrier system, in particular

Backpack, be provided. By the fastening means of the

Functional element carrier are firmly connected to the backpack. The backpack is thus used to connect to the user.

An avalanche rescue system with a functional unit according to the invention also falls within the scope of the invention.

Further features and advantages of the invention will become apparent from the following detailed description of Ausführungsbetspielen the invention, with reference to the figures of the drawing, the invention essential details show, as well as from the claims. The features shown there are not necessarily to scale and illustrated in such a way that the inventive

Fig. 1 shows a schematic representation of a functional unit 1 of an avalanche rescue system. The functional unit 1 comprises a first

Functional element comprising a buoyancy body 2, a gas cartridge 3 and a gas line 4 connecting the gas cartridge 3 with the buoyancy body 2. The gas line 4 opens into a connecting piece 5. The gas cartridge 3 is connected via a pressure control valve 6 to the gas line 4. Furthermore, a locking pin 7 is provided, which is connected to a still to be described triggering system. - -

The buoyancy body 2 has connecting straps 8 with which it can be connected to a functional element carrier to be described later. In the illustration shown, the buoyancy body is the second

folded and compressed.

A second functional element comprises a balloon 9 and a

Gas cartridge 10, which is connected via a valve 11 and a gas line 12 to the balloon 9. The valve 11 also has a

Locking pin 13, which is connected to a triggering system.

The gas in the cartridge 10 is preferably lighter than air. The pressure of the outflowing gas is regulated by the valve 11. At the bottom of the balloon 9 is a check valve. This valve prevents backflow of the gas and causes the gas contained in the cartridge 10 to be completely discharged into the tear-resistant balloon 9. The balloon 9 is connected to an elastic rope, not shown here, which is marked in color. The elastic rope is wound on a pulley, which is connected to a later to be described functional element carrier. This role is characterized by the fact that it allows both an extension and a shortening of the rope. The endangerment of the user by the rope is thereby prevented. The rope has a color scale that divides the rope into three sections without specifying the metric distance to the victim. This means that to accurately determine the position of the buried a point location with

Avalanche probe must be performed and dangerous

Miscalculations of the distance that can occur when metric scaling is used are avoided. The use of an elastic material for the rope prevents any possible injury in the rope Neck of the victim. By filling the balloon with gas that is lighter than air, it allows independence from the principle of inverse segregation, thereby improving the location of a victim.

As a further functional element, a ventilation function unit is provided which comprises a gas cartridge 14 containing liquid oxygen. The gas cartridge 14 is connected via a valve 15 and a

Evaporator 16, which also serves as a pressure regulator, connected to a hose 17. At the evaporator 16, a locking pin 18 is further provided, which is also in connection with a Ausiösesystem. The tube 17 is guided by a variable-length protective cover 19 through to an actuating handle 20. The protective cover 19 is accordion-shaped to realize the Längenveränderlichkeit. The protective cover 19 is fixed to a fixed point 21. Along a carrier belt 22 embodied as a shoulder belt, the hose 17 or the protective sleeve 19 is guided in an insulation jacket 23. This can be formed for example of neoprene. The tube 17 is guided within the protective casing 19 in sections parallel to the actuating handle 20. It then opens into a hollow part 25 of the actuating handle 20, at the end of a mouthpiece 26 is provided. The mouthpiece 26 is made of a flexible material to protect the mouth of a user. The flexible material can not be compressed to the extent that no gas flows through it. Below the mouthpiece 26, openings 27 are provided through which spent breathing air, in particular CO2, can flow out.

The actuating handle 20 is fastened via a locking joint 30 to a carrier system, in particular to the carrier belt 22. Due to the locking joint 30, the operating handle 20 is in its position adjustable, in particular pivotable. The locking joint 30 has on its rear side grooves, which cooperate with corresponding piping 31, 32 to attach the locking joint 30 and thus the handle 20 thereto. Along the piping 31, 32 of the

Actuating handle 20 are also adjusted in height.

When triggered, a portion 25 of the operating handle 20 can be solved or demolished, so that the operating handle 20 to the mouth of the

User can be guided and this can take the mouthpiece 26 in the mouth. In this case, the protective sheath 19 can expand. The length of the tube 17 is sized so that a problem

Supply to the mouth of the user is possible. Alternatively or additionally, the tube 17 may be variable in length.

The operating handle 20 may be attached to a locking plate 33, as

Breastplate is formed, fastened. The locking plate 33 may be attached to a chest strap 34.

To trigger the functional elements is a trigger system 40th

provided, in the illustrated embodiment, a cable or a Bowden cable has (for details, see Fig. 5), which branches up in strands 41, 42, 43, which lead to the locking pins 7, 13, 18. Is therefore pulled on the operating handle 20, the

Retaining pins 7, 13, 18 pulled out, so that gas from the

corresponding cartridges 3, 10, 14 can flow out.

The functional elements are thus triggered simultaneously. In the case of a spill, in addition to a visual location function the

Ensuring the breathing air supply of the buried. In this context, the short window of time between triggering requires Snowboards and the moment in which the winter sportsman is caught by the avalanche, the fastest possible supply of the operating handle 20 to the mouth of the victim. In this feeder, a triggering of the functional elements is automatically realized. Should a functional element malfunction, there are still two more

Functional elements are available that have the chance of survival

Increase burial.

2, a functional element carrier 50 is shown as

Foam plate may be formed n. The functional element carrier 50 has recesses 51, 52, 53, in which components of the

Functional elements are arranged. In this case, the buoyant body 2 via connecting straps 8 fixed to the functional element carrier 50th

connected. The functional element carrier 50 has bushings 54 through which, for example, parts of the triggering system can be guided. The functional element carrier 50 can be releasably connected via fastening means 55 to a carrier system, for example a backpack. In order to facilitate the removal of the functional element carrier 50, gripping tabs 56 may be provided at the upper end. FIG. 3 shows a sectional view through a further plane of the functional element carrier 50. It can be seen here that further

Recesses 57, 58, 59 are provided, in which a

Avalanche rescue bucket 60, an avalanche rescue probe 61 and the cartridge 10 and the balloon 9 are arranged.

The Fig. 4 shows a carrier system 70, which is designed as a backpack, in which the functional element carrier 50 is arranged. It can be seen that an opening 71 for the buoyancy body 2 is provided on the carrier system 70. This opening 71, for example, by a

Velcro fastener, which opens automatically when the - -

Buoyancy body 2 is filled with gas. Furthermore, a bushing 72 for the protective casing 18 including tube 17 and the

Detect triggering system. Basically, it is also conceivable that

Hose 17 with protective casing 18 through a lower

Carry out lead 73 out of the carrier system 70. Already described elements are marked with the previously used reference numerals.

The Fig. 5 shows a detailed illustration of the actuating handle 20.

In particular, it can be seen that the hollow part 25 of the

Actuating handle 20 of a variable-length member 80 is separable. The fact that the part 25 is removable, a false triggering of the functional elements can be prevented. For example, when driving in a nacelle, it may be necessary to disassemble the operating handle 20 so that false tripping can be avoided. Therefore, a sliding element 81 can be provided on the grip part 25, by means of which a latching with a plug-in part 82 can be achieved. On the other hand, the grip part 25 can simply be plugged onto the plug-in part 82 in order to connect the two grip parts 25, 80 to one another. In the region of the sliding element 81, the grip parts 25, 80 can be separated / torn apart when triggered.

Also, the tube 17 together with protective sheath 19 can at the

Position 83 be detachable from the handle portion 25, but must not be solved in a release of the functional elements, of course. The handle part 25 may be provided on its surface with an increased static friction 84 and be rubberized, for example. In addition, it may have troughs 85 which facilitate reliable gripping. - -

It can also be seen that the tube 17 is Z-shaped. This makes it variable in length. It is thus ensured that the tube 17 can be extended so far that a reliable supply of the mouthpiece 26 to the mouth of a user is possible. The protective sheath 19 is variable in length.

The locking joint 30 has on both sides (front and

Rear) grooves 87 on. As a result, it can also be mounted on the other side of a carrier system. By a diaphragm 88, the grooves 87 can be covered.

Furthermore, it can be seen that the triggering system 40 has a wire 89 and a casing 90. Thus, the triggering system 40 has a Bowden cable.

Fig. 6 shows a sectional view through the part 80 of

Actuating handle 20. Here it can be seen that the triggering system 40 is guided in the locking joint 30 and connected to a Teleskopierteil 80.1. The telescoping part 80.1 is within the

Telescoping 80.2 out. In the position shown that is

Teleskopierteil 80.1 fixed in Teleskopierteil 80.2 by the push button 91, which projects through an opening in Teleskopierteil 80.2. The

Length change of the part 80 takes place by the push button 91 is pressed and the Teleskopierteil 80.1 is displaced relative to the Teleskopierteil 80.2 until the push button is locked in the opening 80.3. The length-changed state is fixed with it.

The triggering of the functional elements takes place against the restoring force of a spring element 92, which at one end on the telescopic part 80.1 and at the other end on an extension 93 of the locking joint 30th - - supported. The restoring force is advantageously less than the force which is required for (violent) tearing off of the grip part 25 from the grip part 80.

If the part 80 is pulled to the left, the situation shown in FIG. 7 results. The spring element 92 has been compressed and the pawl 94 engages behind the extension 93 of the locking joint 30. The pawl 94 is deflected by a small spring element 95, so that a

automatic locking takes place when the part 80 of the

Actuating handle 20 is pulled to the left. This lock is felt by a user, so that a haptic feedback occurs. In this situation, the functional elements are released (the cable 89 has been pulled to the left). The triggered position is locked by the pawl 94. The pawl 94 can be released again by a pointed object.

It can also be seen that the locking joint 30 has a ball 96 which is movable in a pan 97. Recesses 98, 99 in the stationary part 100 of the locking joint 30 allow a

Pivoting movement, without affecting the function of the actuating handle 20. Instead of a ball 96 could be provided only a disc, then only a limited pivoting would be feasible.

The Fig. 8 shows in which area the operating handle 20 for

Body horizontal can be adjusted. This allows a user to choose the optimal angle. In particular, a pull angle of the operating handle 20 can be set in the range of 0 ° - 30 ° to the horizontal body. The adjustable draw angle supports the ergonomics - - at the time of triggering and can prevent erroneous gripping of the actuating handle 20.

The illustration of FIG. 9 can be seen that the

Actuating handle 20 by a locking means 101, such as a Velcro, can be locked to the locking plate 33 in the retracted state.

From Fig. 10 it can be seen that by another

Locking means 102 and a lock in the extended state of a breast plate 33 is possible.

While in the previous illustrations the use of the

Actuating handle 20 was shown on the left side seen by the user, Fig. 11 shows that the operating handle 20 is also mounted on the right side. In particular, this is the

Locking plate 33 right / left usable. That too

Arretierungsgelenk 30 can be mounted on two opposite sides and is designed accordingly. Thus, the actuating handle 20 according to the invention and the functional unit can be used both for right-handed and left-handed.

Fig. 12 now shows a user who has triggered the functional elements. In particular, it can be seen that the buoyant body 2 is inflated and wider than the user. The neck of the user is enclosed by wings 110, so that the neck area is protected. Here it can also be seen that the buoyancy body 2 has a Venturi nozzle 111, by which a complete inflation of the buoyant body 2 is ensured. The user has torn the operating handle 20 from the anchoring on the telescoping 80 and the mouthpiece 26 in shut up. The balloon 9 was inflated and the rope 112 at least partially unwound. The carrier system has in the illustrated embodiment, not only a hip belt 113 but also

Leg straps 114 on.

FIG. 13 shows an alternative embodiment of a handle 200. The handle 200 is substantially T-shaped, wherein the legs 201, 202 are angled relative to a base leg 203. In particular, the leg 202 to the base leg 203 at an angle of less than 90 ° and the leg 201 has the base leg 203 at an angle of more than 90 °. In leg 202, an air channel 204 is formed, through which the ventilation function can be realized. The handle 200 is therefore partially hollow. To the leg 202 is to be described in more detail mouthpiece. It can also be seen that two cables 205, 206 designed as Bowden cables are arranged on the handle 200. As needed, both or only one cable 205, 206 can be connected to the handle 200. In particular, the cables 205, 206 are detachably connected to the handle 200. For example, one of the cables 205, 206 may also be used to actuate an electronic operating mechanism for a functional element. It is also conceivable, instead of one of the cables 205, 206 to use an activation cable for an electronic triggering mechanism.

FIG. 14 a shows a mouthpiece arrangement 210 with a mouthpiece 211 and a connecting piece 213 which is arranged on the actuating handle 200. The mouthpiece 211 is connected via the flexible connecting piece 213 to the actuating handle 200, in particular the leg 202. If an emergency situation occurs and if a ventilation function has to be implemented, then the mouthpiece 211 can, as shown in FIG. 14b - - Is shown, are moved relative to the leg 202, in particular a piece are pulled out. This is possible because the flexible

Connector 213 is used. In the present case, the flexible connector 213 is formed as a concertina-like tube. The mouthpiece 211 can now be arbitrarily moved and displaced relative to the leg 202, so that it can be optimally fed to the mouth of a user.
